Title: Drift eliminator particularly for a cooling tower
IPC: F28C1/04
Filed: 1972-06-28
Abstract: 1366442 Removing water drops from air ECODYNE COOLING PRODUCTS CO 28 June 1972 [9 July 1971] 30262/72 Heading BIT [Also in Division F4] A drift eliminator adapted to remove entrained water droplets from air, particularly the air outlet of a cooling tower, consists of at least one pair of blades 28 of cellular structure and disposed face-to-face to define between adjacent blades a through-passage of which a portion is inclined to the general direction of air flow so that the air impinges on the blades which have longitudinally extending projections 45 to trap the water droplets and prevent them being carried along the blade surface by the air stream. Fig. 4 shows a typical blade providing with a similar blade a generally V-shaped passage 55, Fig. 3. The blade has rounded leading and trailing edges 38; and is of plastics material, e.g. P.V.C. or polypropylene. The projections 45 protrude by about 0.02 inches. The blade assembly is held between supports such as 52 by pins 65, Fig. 7. Each pin has a bifurcated shank 67 which extends through a suitable hole 62 or 64, Fig. 3, in the support and grips an internal stiffening member 39 or 41 of the blade. The blades are longitudinally inclined by about 10‹ so that water collected by the projections 45 runs to one side of the assembly where it drains away through the holes 64 in the supports 52, these holes being shaped to permit water to pass therethrough whilst still allowing the head 66 of the pin 65 to be seated on the support member 52. The eliminator is said to be applicable to either crossflow, or counterflow cooling towers.

Title: Improvements in or relating to apparatus for treating plastic substances
IPC: B01F13/00
Filed: 1920-10-28
Abstract: 174,711. Flood, S. Oct. 28, 1920. Extrusion machines.-Comprises a cylindrical casing, a cylindrical element rotatable in the casing, and blades slidable in the element and reciprocated parallel to the axis by helical surfaces, the element, blades and helical surfaces combining to form chambers the capacity of which dimirishes as the element rotates, so that material fed into the chambers is squeezed and extruded through appropriate outlets. In the construction shown in Figs. 7 and 9, a cylindrical collar 5 secured to a shaft 4 makes a good rubbing fit with the interior of a cylinder 1, and is formed with longitudinal slots 6 in which blades 7 are free to slide. The ends 2, 3 of the cylinder 1 have helical or " camshaped " inner surfaces so arranged that as the shaft rotates, the blades 7 are reciprocated in their slots but always remain in contact with the surface 2. Material to be treated is fed from a hopper 10 into the chambers formed between adjacent blades. The capacity of the chambers is reduced as the shaft rotates so that the material is squeezed and extruded through a discharge passage 8. The central shaft is made hollow to permit steam heating of the machine, and a port 26 is provided in the member 3 for the relief of material which may work behind the plates 7. Ports 28 may be provided in the blades in order to prevent the material from being subjected to excessive pressure. Instead of utilising the inner surface of the member 3, the blade 7 may be kept in contact with the member 2 by means of springs or by means of a cam groove, formed on the inside of the cylinder, which is engaged by projections in the blade 7. In a modification, a space is provided between the peak of the surface 2 and the collar 5, and the shaft is movable longitudinally, so that the collar can be moved to extend the material. The collar may be fitted with two rows of blades reciprocating on opposite directions, in order to knead the materials. The blades may be triangular in shape, and they may also slide through pinion wheels which are rotatably mounted in the collar 5 and engaged with an internally toothed wheel secured to the interior of the casing. Thus the blades rotate on their axes as the collar rotates and churn or knead the material.

Filed: 1948-11-24
Abstract: 663,779. Sawtooth generating circuits. COPE, J. E., and GERMANY, L. W. Nov. 21, 1949 [Nov. 24, 1948], No. 30572/48. Class 40 (vi). Negative feedback for the output valve of a scanning wave generator is obtained from an amplifier fed from a feedback transformer connected in series with the deflection coils and the output transformer of the generator. As shown the primary of the feedback transformer T2 is connected between the two halves of the secondary of the output transformer in parallel with two resistors R3 and R4 and the secondary feeds an amplifier valve V2 which applies negative feedback to the grid of the output valve. A potentiometer P and a resistor in the grid circuit of valve V2 adjust respectively the amplitude and linearity of the seaming wave. It is stated that the feedback makes the output waveform independent of the length of cable feeding the deflection coils. Specification 518,378 is referred to.

Title: Current steered logic circuits
Inventor: DUNN ROGER STANLEY
IPC: H03K19/086
Filed: 1963-08-01
Abstract: 1,071,293. Logic circuits. TEXAS INSTRUMENTS Ltd. July 17, 1964 [Aug. 1, 1963], No. 30640/63. Heading H3T. In current-steered logic circuits of the type in which two alternative transistors switch the current through one output transistor, and a further transistor switches the current through another output transistor, the input electrodes of the switching transistors are provided with coupling resistors for supplying the switching-off current and the output transistors do not conduct unless an external circuit is joined to their output terminals This arrangement reduces power consumption and false triggering by noise compared with known circuits of this type (Fig. 1, not shown) where the output transistors have load resistors permanently in circuit and the input terminals of the switching transistors are left floating. In Fig. 2 a current source I feeds one output transistor VT4 through two parallel switching transistors VT1 and VT2 to which input signals are applied at A and B to give an output at X. Another switching transistor VT3 inverts the polarity to give a complementary output at Y. The switching transistors are all supplied with base resistors R3, R4, R7, the bias on VT3 being also controlled by VT6, R5 and R6 to reduce the effect of supply voltage variations and the finite internal resistance of I. The reduced input impedance of VT1 and VT2 reduces the effect of noise since these transistors are held non-conducting in the absence of an input connection. In a modification (Fig. 3, not shown) the base of VT6 is connected to the collectors of VT1 and VT2 instead of to a potential divider across the supply. This provides a triggering action so that noise signals too low to operate the trigger will not cause false operation. In connecting the output to a plurality of further logic circuits (Fig. 5, not shown), each of the latter has its own input resistor and does not have to be supplied by the power source of Fig. 2.

Abstract: 621,585. Spinning spindle apparatus ; bobbins. BRITISH THOMSON-HOUSTON CO., Ltd., and CLOUGH, F. H. Oct. 15, 1946, No. 30674. [Classes 120 (ii) and 120 (iii)] The upper bearing of a spindle shaft is pivoted to allow the shaft to be swung sideways for doffing, when the bottom support for the shaft is lowered clear. The invention is applied to spindle apparatus in which yarn is fed to a pirn through guides in a funnel-shaped member fixed to the top of the spindle shaft. The shaft 1, Fig. 1, is mounted in a ball bearing 5, pivotally mounted at 5a, and is driven by an electric motor 6, resiliently mounted on a reciprocatable rail. A sleeve 7, fixed to the rotor of the motor 6, surrounds the shaft 1 which is splined for engagement by a driving washer 8 secured to the sleeve 7. A pirn-carrier 13 is mounted on a ball-bearing 18 on the end of the sleeve 7 and carries a brake disc 20 which co-operates with a drag-magnet for retarding rotation of a pirn 10, to enable yarn to be wound onto the pirn as it leaves a passage 3, 4 in a funnel-shaped member 2 fixed to the shaft 1. When the pirn is fully wound, the motor is stopped- and the reciprocatable rail is moved down until the carrier 13 is clear of the shaft 1, the pirn is then slid upwards and the shaft 1 pivoted sideways to allow the pirn to be slipped off, Fig. 6. Instead of the drive to the shaft 1 being at the bottom it could be at the top of the shaft and be either direct or indirect. The pirn 10 is constituted by a paper tube impregnated with a synthetic resinous material and provided at its upper end with a selflubricating bearing 11 and a metal reinforcing cap 12. A reinforcing cap 14 is fitted at the lower end and is provided internally with an annular groove 15 to be engaged by a catch 20a on the carrier 13. Specification 621,600 is referred to as describing and claiming a driving means for spindle apparatus of this kind.
